Description

The electronic watch that simulation shows

The present invention relates to have such table that relates to of electronic watch and particularly (but being not single) that simulation shows.The great majority that occur have the electronic watch that simulation shows at present, and its indicating mechanism is driven by single bipolar single-phase stepping type electromagnetic motor, and this motor only responds the pulse of alternating polarity usually with the rotation of 180 ° of stride sensitive ranges.

In such definite epoch motor, the rotor that comprises the permanent magnet of a band garden cylindricality diametrical magnetization, with a stator, this stator is formed by two pole shoes, two pole shoes are made of two particular components in a plane, and polar surfaces that this flat table reveals is as the part around the garden column casing of stator, and endways both sides are separated by break joint between the pole shoe, with lead a magnetic core is wound on the stator, so that the pole shoe of stator is fixed.

In addition, the pole shoe of stator is provided with in such a way, promptly make their polar surfaces on opposite direction, depart from slightly so that rotor produces two well-defined rest positions that are mutually 180 ° of angles with respect to rotor rotation, and the magnetic axle of rotor with and bipolar shoe between divide gap to be connected axis form and be similar to 45 ° angle.

In fact above-mentioned these motors exist important disadvantages.

In fact, move in optimum range in the mode of determining, be necessary their off-centre of polar surfaces of pole shoe is regulated accurately in order to make them.

In order to achieve this end, need at first motor to be installed on their bearing, base plate for example, base plate is provided with stud, pole shoe can rotate around stud, secondly by means of eccentric and special instrument set base plate is regulated, by screw these pole shoes are fixed on the bearing at last.This adjusting has so spent the plenty of time.In addition, need demonstrate the motion of table in some way, so that can see being positioned at the other pole shoe part of rotor and having the inlet that leads to eccentric and locking screw, a bridge circuit is provided like this, and this bridge circuit remains on rotor in fact can be as the position of other purpose.At last, when needs dismounting table maybe when table when being given a shock, just must not no longer carry out and above-mentioned adjusting identical operations.

For this reason, this motor can only use in the very short time cycle, and this motor has been made way for those the sort of easy productions that can find and the motor of application in present table.

In fact these present motors take three kinds of forms, and the difference of they and the sort of motor discussed above only is their stator.

The simplest and present the most general be those motors that have a stator, described stator is formed by the single member that downcuts from soft magnetic material, its core comprises a cavity that is actually column casing shape inwall, rotor coaxially in the cavity.In these motors, self connects by chance by neck between the pole shoe, be that narrow can reach capacity easily and promptly by the magnetic line of force, the excentricity that in fact this neck member has played the part of role identical with said motor pole shoe break joint and above-mentioned pole shoe replaces by the shown groove of stator inner wall or with radially relative evener branch.

Can from certain table, see in the form of still rarely found other two kinds of bipolar single-phase motors people, can find the idea of two unique pole shoes once more.

In one case, these pole shoes demonstrate the skew polar surface same with old-fashioned motor mentioned above, but be the insert by nonmagnetic substance this moment between these polar surface self connects and welds in the both sides of stator idol, perhaps constitutes a monolithic stator in fact in some way.

In another case, these pole shoes are separated continuously by break joint, their polar surfaces is then no longer setovered as some part of column casing shape and groove is set to determine the static position of rotor on polar surfaces, motor comprises the cylindrical sleeve of another one nonmagnetic substance, this sleeve is fixed on the substrate that motor is installed, and this sleeve is coaxially around rotor and as the location and the support component of pole shoe.

No matter The above results by what mode obtains, advantage such as that these bipolar single-phase motors all have simply, take up room is little, cost is low, but they have also showed important disadvantages.

When they normally being used for table, promptly when people from design point of view with when allowing on the meanings such as improvement of indicating device their action pleased oneself, want to change display message and above-mentioned the free setting mechanical hook-up of just having to be provided with, this mechanical hook-up can proofread and correct hasten forward or the hysteresis situation under time indication, perhaps electric installation, this device is guaranteed only upwards to proofread and correct at folk prescription.Under second kind of situation, motor is by the pulsed drive of fixed frequency or the pulsed drive that changed by the operating speed of control elements conveniently during the correction, and these pulses are obviously greater than with the received pulse of normal manipulation mode.In order to make it respond each correction pulse, it is enough low that this frequency must keep, and is no more than 32 or 64Hz usually, thus for realizing proofreading and correct the table that the time that spends may quite grow and be not suitable for second hand.

The most ripe scheme that has solved effectively in practice or partly addressed this problem has two kinds.

First kind of scheme comprises keeping same bipolar single-phase step motor and controlling it by particular form makes its produce antiport.Like this, people can only acquire an advantage from the advantage of this motor continuously, but just seem extremely general in the operating performance on the opposite direction with respect to the performance that is obtained in the normal forward operation.

Second kind of scheme is to adopt 4, No. 371821 disclosed the sort of reversing motors of United States Patent (USP), and there is not above-mentioned difficulties in this motor.

This motor that still rotates with 180 ° of strides comprises the rotor identical with single-phase motor, with the monolithic stator that has three pole shoes, be connected by neck between three pole shoes, stator itself is in fact also as the cylindrical cavity of rotor case, and two rest positions of the groove that on inwall, has a surrounding cavity when determining that rotor comes 180 ° of back rotation, two magnetic cores that twined by two leads link to each other a pole shoe respectively with two other pole shoe.This motor is compared obvious volume with single-phase motor big and manufacturing cost is high.

These two kinds of schemes can realize electrical time setting, for example carry out fast fast time district and change in the watch that only comprises minute hand and hour hands, but unfortunately they can not be used for having the table of second hand and/or date indicator so far.

This is one of reason that not long ago began to produce driving indicating mechanism that has two motors or the table that drives indicating mechanism's group respectively.

Another reason is to save obtained energy.In this case, especially his-and-hers watches wherein two motors be used to drive second hand and minute hand on the one hand, drive hour hands and date indicator on the other hand, perhaps his-and-hers watches, date disc is by second motor driven by first motor driven for second hand wherein, minute hand and hour hands, but people have to abandon the electrical set of time and date for this reason.

The 3rd reason be people so easily the function quantity that can finish of increase table as clock, warning etc.

At last, the 4th reason is to reduce the quantity of wheel based part in table.

At present, in order further to benefit, in fact no longer be confined to present single motor from all advantages, people have begun to make and have comprised four even the table of five motors sometimes.

Difficulty is clearly, and for example two motors will spend the cost of twice compared with single-motor and occupy the space of twice in table, or in fact two motors are incomplete same.

This has explained how people have realized making motor to have the idea of a shared stator and two or more rotors soon.

In other words, the delay of the bipolar single-phase motor of being discussed during at least owing to beginning, people common practice in making flat stator or pole shoe with the soft magnetic material plate, provide desired shape by simple or continuous processing, then their integral body is placed anchor clamps and heat so that they are carried out annealing operation handles at stove, this operation can make the material matted crystal that forms stator reconfigure to eliminate inner mechanical stress etc.; In other words, recover in moment of annealing operation because distortion and or the good magnetic of the material that loses less of many one-tenth.

Now, this mode of operation has produced a problem.In fact, flat stator or their polarity boots always have the part of relative fragility.This situation refers in particular to the prerequisite suspended wall die of pole shoe, and this die is more or less around stator, or the neck of monolithic stator.Therefore, at these stators or these pole shoes by the moment that integrally places anchor clamps or take off from it, perhaps even the most simply when they in transportation during by skew, produce certain deformation or fracture always so that they can't be used again, this has caused those motor prices that are kept perfectly to increase.

In addition, the quantity of stator and its fragility that is comprised part is many more obviously, and the danger of distortion and fracture is big more, and the loss that each waste product caused is big more, and the production cost that should consider and the regular investment that is used to develop are also just big more.

Like this, for the stator of the motor with two rotors that provides at present, the problems referred to above are very important, if very close with rotor arrangements for the quantity that reduces train as much as possible in being provided with the table of this motor especially.

In order to address this problem, can use existing program to eliminate the adjustment difficulty of single-phase motor fully, described motor has the biplate stator of discussing the front, and this scheme can be eliminated the existing problem of motor simultaneously.

This forecast scheme configuration BrP 1,457,676 theme, and two to three years have been used, stator is made up of a member that has cavity that downcuts from the soft magnetic material plate at first, and the inside and outside profile of this member and the stator pole shoes shape and the relative position of the desired acquisition of people fit like a glove.Then this member is soldered on the back up pad of nonmagnetic substance fully, the exterior contour of member is due consistent with it on large scale, so that can before welding, carry out position correction to it, hole, a garden is arranged on this member, the hole, garden is on every side around having formed cavity wall.After this, thus carrying out die-cut operation further obtains break joint that two pole shoes are separated and assembly is heated so that stator is carried out annealing operation.In fact, for make pole shoe during annealing and the moment of cooling be not subjected to stress and distortion, and in order to make them keep correct position mutually, be necessary to select to have equally or the supporting plate material of almost same thermal expansivity with stator.

With respect to the way of front, this back up pad has also played to be strengthened stator pole shoes and protects it to make its complete effect.

In addition, this plate and any flat stator might be linked to each other fully and make it to play the effect identical and will limit the size of this back up pad so that make it only cover the fragility subregion of stator with stator.

Simultaneously, if be satisfied with operation by this way, will run into two other problems.

First, if gusset plate can be effectively is certain by fully eliminating the situation that a large amount of stator costs that the waste product that is produced by annealing reaches expection reduce practically, and no matter the price of these gusset plates how and be that they are connected with stator or stator is connected with them, this situation is less generation for little and inexpensive small size stator and the pole shoe of cost of fragility, and it is no longer very frequent with the way of the parts of avoiding losing certain ratio that gusset plate is set in this case.This way sometimes or even fully uneconomic and can therefore lose whole profits.

Second problem is when in table or other clock and watch this plate being set, and this plate only becomes the number of spare parts of increase table with the element that takes up space and without any other purposes.

The purpose of this invention is to provide the scheme that solves above-mentioned two problems.

This purpose is by following true the realization, according to the present invention, in clock and watch, comprise a special electromagnetic motor, this motor has at least one permanent magnet rotor, this rotor is installed on the rotary body that sways, basically a flat stator comprises at least two pole shoes, this pole shoe partly centers on rotor and in fact they is arranged perpendicular to rotation axis, a coil is magnetically received stator by chance, be used to show the indicator of temporal information, be used to move ground with the even train of receiving motor of this device indicating, and motor in fact also comprises the gusset plate that is used for motor stator, this gusset plate is connected to pole shoe and partly covers the pole shoe that closely centers on stator from an end of stator, and this gusset plate comprises such device, and this device can constitute at least one other parts of table simultaneously.

Above-mentioned parts can be the pure machinery that hereinafter will describe, and perhaps electricity is for example as the contact that electrically contacts.

Like this, thereby other parts that can save at least one table of making and installing are when last application has the motor of a big stator, can produce an economic effect that adds, and the utilization of gusset plate has produced tangible advantage for the small size stator.

Can understand the present invention better by the description of reading following two embodiment, this is described with reference to the following drawings.

Fig. 1 is the vertical view of a stator example, and this stator is used to cover with the motor of two rotors and by gusset plate, and gusset plate provides a kind of another kind of form of electronic watch hand-control device part, in table above-mentioned motor and this plate is combined;

Fig. 2 partly represents a stator, and this stator is different with stator shown in Figure 1.

Fig. 3 is the synoptic diagram of the appropriate section of above-mentioned table;

Fig. 4 is the part section enlarged drawing along dot-and-dash line IV-IV among Fig. 3, has wherein added the indicating device of table;

Fig. 5 is the partial top view of another kind of table, and this table comprises a bipolar single-phase motor that is covered by gusset plate, and the setting of gusset plate is in order to form a bridge circuit that adds;

Fig. 6 is the part sectioned view along dot-and-dash line VI-VI of Fig. 5, other external parts of its expression table.

As shown in Figure 1, the flat stator 2 that is used to have the motor of two rotors is the monolithic configurations that formed by for example iron-nickel alloy.Described alloy is such as the product of commercially available trade mark for " VACOPERM " or " PERMIMPHY ".

This stator can be thought by P ₁And P ₂Two parts constitute, and are separatrix and vertical each other the setting with the A-A line wherein, as United States Patent (USP) 4,371,821 theme quote as proof like that, these two parts are all corresponding to the stator of reversing motor.

P ₁In fact part has three pole shoes 4,6 and 8, be connected with 14 by neck shape part 10,12 between them, by the inwall 18 that in fact is the garden cylindricality around cavity 16 form by pole shoe and neck shape portion, and in order to accommodating the rotor with permanent bipolar magnet, two radially groove opposite 20a and 20b are arranged on the inwall 18 to produce two rest positions that are mutually 180 ° for rotor.

In addition, at P ₁On be processed with four through hole 22a, 22b, 22c and 22d so that for example be screwed two magnetic cores, each magnetic core is all twined by coil, this coil pole shoe 4 respectively idol receive on pole shoe 6 and 8, magnetic core is positioned at the both sides of pole shoe 4 and parallel with line A-A.

Equally, the P of stator 2 ₂Part comprises three pole shoes 24,26 and 28, and they correspond respectively to P ₁The pole shoe 4,6 and 8 of part still only has the very little difference except pole shoe 24 and pole shoe 4, and other parts neither have identical shape and also do not have identical size.

At P ₂Part can be found 3 neck shape parts 30,32 and 34 equally, and they connect pole shoe 24,26 and 28 in pairs by chance, and cavity 36 is formed by the inwall 38 that in fact is the garden cylindricality, this inwall and P ₁The inwall 18 of part has identical diameter and is with the shell of the rotor of bipolar magnet as another, two groove 40a and 40b are radially arranged on the inwall 38, through hole 42a, 42b, 42c and 42d are as the web member of two other magnetic core, described magnetic core is twined by two other coil, coil is received pole shoe 24 idols on the pole shoe 26 and 28 that is positioned at pole shoe 24 both sides, and magnetic core is vertical in fact mutually with line A-A in this case.

In addition, stator and P ₁And P ₂The part layout and arrange as follows:

1, two pole shoes of A-A connection along the line are pole shoe 8 and 26;

2, pole shoe 8 is obviously greater than other pole shoe, so that a turning 44 and straight flange 46 that begins from line A-A that is approximately the right angle that stator is had determine according to it, this straight flange has a projection 50 to contact with limit 46 perpendicular to another straight flange 48 on the limit 48;

3, cavity 16 is mutually close each other with 36, they be centered close to one in fact with the perpendicular straight line of line A-A on; With

4, pole shoe 28 is close to each other with pole shoe 6, and separate, stitch 52 by break joint 52 and have the parallel edge that is oriented in line A-A direction and extend to the inside of stator and form neck 14 and 34 thus by cavity 54, by this neck with pole shoe 6 and 28 respectively idol receive on pole shoe 8 and 26.

In addition, stator 2 comprises two other cylindrical holes 56 and 58, and its purposes will be narrated below.At first, hole 56 is positioned at the bottom of cavity 54, and is provided with its axis and cavity 16 and 36 equidistant modes, and the second, hole 58 is smaller, and it is set at the end of projection 50.

Observing Fig. 1 can easily find, because cavity 16 and 36, break joint 52, cavity 54 and 4 dark or shallow grooves 60,62,64 and 66 separate pole shoe 4 and 6,4 and 8,24 and 26 and 24 and 28 respectively, it is fragile especially that the whole zone of this stator all seems around all openings, therefore be easy to generate bending and distortion especially in these zones, particularly in the place of the most close neck 10,12,14,30,32 and 34, when stator is operated with other parts, if neglectful words are easy to rupture.

This has proved foregoing situation, and for comprising two motors near the rotor of location, it is very necessary that gusset plate is set.

In this case, gusset plate by label 68 representatives is formed by main part 70, its effect is to prevent that stator 2 from producing distortion and fracture, in order to reach this purpose preferably by welding or bonding gusset plate and stator are rigidly fixed, two tongues are attached to this main body, and tongue itself does not link to each other with stator.

On the other hand, plate 68 has the thickness that is significantly less than stator 2, for example less than 1/3 of stator thickness, and the material that forms this plate is not limited only to nonmagnetic substance, its thermal expansivity equals or is approximately equal to stator material, and has enough elasticity so that tongue 72 and 74 can be easily crooked.When stator was actually " VACOPERM " or " PERMIMPHY " material, the trade mark that plate 68 can preferably be sold by IMPHY company was the beryllium copper or the steel of " PHYNOX ", and this steel is the alloy of iron, cobalt, chromium, nickel, erbium.

For main body 70; can find that it has almost completely covered pole shoe 6,26 and 28; gap 52, cavity 54 and groove 60,62,64 and 66 also part cover pole shoe 4,8 and 24; wherein be enough solid and firm to greatest extent from cavity 16 and the zone of opening in 36 minutes so that do not need protection, be drilled with 7 cylindrical hole 76a, 76b, 78a, 78b, 80,82 and 84 on the main body 70 respectively with hole 22c, 22d, 42c and the 42d of magnetic core and coil stationary and cavity 16 and 36, hole 56 is coaxial.

Can also see, the Kong Yaoda on the stator that the hole on the main body 70 is all aimed at than them, and when from hole 76a, 76b, 78a and 78b to the hole 80 and 82 and during to hole 84 its diameter difference increase.

With regard to hole 80 and 82 and cavity 16 and 36, notice that above-mentioned difference is very interesting, in fact this diameter difference is enough to make gusset plate 68 in fact neither to cover neck 10,12 and 14 also not cover neck 30,32 and 34.This does not influence the normal protective effect of gusset plate, because the pole shoe that is connected with them interfixes generally.

On the free part on main body 70 right sides of the turning 44 of stator and plate 68 two tongues 72 and 74 are set, their extend along the direction on the limit 46 that almost is parallel to the turning.Almost reach the height on limit 48 and be in the projection 50 that it stretches from limit 46 tongues 74 far away.On the other hand, very near limit 46, its terminal exceeds limit 48 to tongue 72, and end 86 abuts against the right of projection 50, end 86 is crescent and inner face has two little circular protrusions, and two projectioies form two grooves 94 and 96 between self and between they and the crescent top 92.

Break joint 52 is set between the pole shoe 6 and 28 of stator obviously is and be used for constituting high magnetic resistance district and two parts magnetic circuit of motor is insulated between bipolar shoe, said two parts are corresponding to the P of stator ₁Part and P ₂Part.In other words, if do not encourage them simultaneously but the employing alternative excitation, these two parts of motor just can not move respectively and exactly, consider that from the angle of energy consumption this is highly significant for situation of using two separate motors.

Problem is when being connected to gusset plate on the stator, because being provided with of break joint 52 may make pole shoe 6 and 28 can not be based upon in the same plane fully, therefore this connection may not be very good and may fail in this zone, concerning stator, there is the danger of certain deformation and fracture simultaneously, generation for fear of this situation, can do by shown in Figure 2, promptly two neck 98a and 98b are set directly when forming stator so that between them the machinery idol connect and form pole shoe 6 and 28.From the angle of motor two parts operation, this does not almost have any variation.

If observe part from the top of Fig. 3 at this table that occurs, will debate out that indicate and be installed in this motor on the printed circuit board (PCB) 102 in a suitable manner at an easy rate by label 100, motor is provided with stator 2 and four magnetic cores 104,110,116 and 122 that gusset plate 68 has been installed, be wound with coil 106,112,118 and 124 on the magnetic core respectively, magnetic core meets stator P with mode idol mentioned above ₁And P ₂Two-part different pole shoe, and with screw that 108a and 108b, 114a and 114b, 120a and 120b and 126a and 126b is fixing one by one.

On the other hand, on this figure, can't see the generation type of two rotors.In order to understand this point better, have and must describe with reference to accompanying drawing 4, indicating device that Fig. 4 represents and train, by train by two rotor driven indicating devices.

If at first observe the left-hand component of Fig. 4, just can determine the rotor portion 128 of motor 100, the pole shoe 8 that belongs to the stator 2 of motor is placed in the little caisson 130.This caisson comprises the hood-like member 132 of nonmagnetic substance, and nonmagnetic substance can be a beryllium copper for example, and this member is embedded into by pressure in the cavity 16 of stator and by flange 134 and limits moving of it, flange 134 by the wall in the hole on the gusset plate 68 80 around.The bottom 136 of member 132 is drilled with a center pit so that form first supporting 138 of rotor.In addition, the opening portion of this member is covered by plate 140, a center pit is also arranged to constitute second supporting of rotor 128 on the plate 140.

Rotor 128 comprises axle 144, on the axle bipolar magnet 146 is housed, and an end of axle constitutes pivot 148 and meshes with supporting member 138.The bigger end 150 of another of axle extends by supporting 142 and by two end-journal 152a and 152b, and two end-journals play the gearing of output pinion.

Obviously, at first rotor 128 is installed in the caisson 130, then it is fixed on the stator, can during whole erection, avoid the thorny operation of rotor with respect to stator centering.

If observe the right-hand component of figure now, can see that second rotor 154 is the same with the first rotor and pack in another caisson 156 that caisson 156 embeds stator another part P in identical mode ₂Cavity 36, but opposite with above-mentioned situation, two end- journal 158a and 158b are arranged on the opposite side of stator with respect to supporting gusset plate 168 and pivot.

Continue to observe Fig. 4, the cylindrical hole 56(that can find stator between two rotors 128 and 154 is referring to Fig. 1), be embedded with an end of pipe core 160 in this cylindrical hole, pipe core is to the extension of the front portion of stator 2 and have an axle collar 162 that embeds the hole 84 of gusset plate 68, and gusset plate 68 is supported at the front surface of stator.

Split axle 163 passes through in pipe 160, and at an end of split axle and the rear support minute wheel 164 of stator, minute wheel is meshed with the end-journal 158a and the 158b of rotor 154.

Axle 163 keeps axial location by the axle collar 166 in pipe 160, the front of the axle collar is a wheel 164.Stop collar 70 has flange 172, and flange is forced on the collar 168 and with minute hand 174 and joins.

At last, the hour wheel pipe 176 that has pipe 178 is installed on top at pipe core 160, this pipe carries out axial retention and supports hour hands 182 by managing 160 the axle collar 162 and the flange of the collar 170, and hour wheel 180 is fixed on the pipe 178 and with the end-journal 152a and the 152b of rotor 128 and is meshed.

Refer again to accompanying drawing 3 now so that describe hand-control device, hand-control device is set is not only electrical time setting in order to show, and to select and control at least one function except the indication of normal time, this purpose can be easy to realize by motor and the pointer that is provided with above.

This device comprises arbor 184 rotatable and that slide, a location resetting system, can make arbor between centre position or rest position, produce axial displacement by this system, above-mentioned position is generally pulls out stable position and pushes the unstable state position, the switching system that can trigger, this system provides electric control and correction signal.

Control arbor 184 comprises is convenient to button 186 and targeting part 188 that arbor is handled, arbor passes watchcase 190 by targeting part, only watchcase has been done very locally and schematically shown among the figure, guaranteed that in through hole 192 arbor is moving and the guiding of rotation direction and determined the position that pushes of arbor by means of stayed surface 194, this stayed surface appears at a side of button, and the following part of button can push in the watchcase.In addition, a ring groove 196 is being set so that between targeting part and watchcase, put into packing ring 198 on the targeting part 188 usually.

Furtherly, arbor 184 comprises that also two cams 200 and 202, two cams are fixing side by side, and a groove 204 is arranged between second cam 202 and lasso 206.

Cam 200 and 202 and United States Patent (USP) 4, those cams that constitute electronic watch part control device that 379,642 theme is discussed are similar, promptly, in fact they be ellipse garden shape, the axis of cam by they the center and also the main shaft of two cams between be about 45.

On the other hand, arbor 184 is provided with in such a way, promptly make lasso 206 and groove 204 very near the stator projection 50 on the motor 100, this projection is relative with the end 86 of tongue 72, and this groove 204 simultaneously or almost simultaneously is tangential to a plane that makes stator front surface and location, rear portion.

The location of arbor and resetting system comprise two a flexible tongue sheet 72 and 74 that draw shelves 208 and gusset plate 68.

Draw shelves 208 to constitute by a flat components, it can rotate around stationary shaft 210, axle 210 holes of passing on the stator projection 50 58 are drawn shelves always to keep or are almost always kept contacting so that tongue 72 is connected with the groove 204 of cam with 74 with stator by means of this.

For this reason, draw shelves to comprise an annular center part 212, this part is around axle 210 and produce three branches 214,216 and 218.First branch 214 and groove 204 engagements also have definite shape so that the rectilinear motion of arbor is transformed into draws rotatablely moving of shelves, allow this arbor portion freely to rotate simultaneously.Second branch 216 is positioned on the extended line of first branch roughly, and it is triangular in shape substantially and have a termination of rounding, and this termination always contacts with the inward flange of the end 86 of tongue 72 and can place in the middle of any of two grooves.The 3rd branch 218 has and second branch's similar shapes, its set-up mode be make its core the edge can or can be not do not contact with tongue 74 in a side of the main body 70 of gusset plate 68.

When control arbor 184 is positioned at the centre position, draw the edge of shelves the 3rd branch 218 to touch with the side edge of tongue 74 simply and make arbor be in rest position, and when groove 96 engagements of the end of second branch 216 and tongue 72, arbor also is in static position.

Let us imagination, the arbor actual fixed is in this centre position and be drawn out.As long as the pulling force that applies is not large enough to the top that causes branch 216 and crosses over projection 90 and make tongue 72 bendings, draw shelves 208 just can not rotate and this top will remain in the groove 96, perhaps when discharging arbor, will make and draw shelves to reset if the top has produced slight separation.On the other hand, if pulling force greater than a certain determined value, draws shelves to rotate in a clockwise direction, the top of its branch 216 is positioned in another groove 94 of tongue 72, and branch 218 separates from tongue simultaneously.

If after successfully arbor being placed the pull-out location, continuation applies correct tension to it, will prevent that than another projection 90 big projectioies that many 88 top of branch 216 from skidding off from groove 94 on the tongue 72 so, projection 88 has the another kind of shape that is suitable for this purpose.

In the same way, be returned to the centre position for making arbor, be necessary to exert pressure on button 186, this pressure is enough to cause and draws shelves 208 to rotate and make the top of branch 216 get back in the groove 96 in counter-clockwise direction.

Tongue 72 has constituted a bungee that is used to draw shelves like this, when drawing shelves to mediate and it guarantees to draw shelves to be in locked position during in the pull-out location.

Now hypothesis is exerted pressure on button 186 so that arbor arrives its pushing in device from its centre position.Draw that shelves 208 are stressed to rotate in counter-clockwise direction, cause when branch 218 is supported on tongue 74 and to force tongue to produce crooked; Simultaneously another branch 216 outwards moves and separates from the end of tongue 72 pushes up the groove 96 of 92 1 sides, and this also forces tongue 72 to produce slight bending.
